7 Claims. (01. 98-115) This invention relates to ventilators of the type employed for collecting and disposing of smoke and cooking odors arising from cooking stoves and it has particular reference to improvements in such ventilators and the mounting facilities thereof.

Ventilating canopies mounted above cooking stoves and ranges for carrying oif grease laden smoke and odors are quite old but as far as is known, no installation of this type possesses an initial supporting fabrication'or mounting so designed and constructed that it may be located relative to wall studding and aflixed thereto for greater permanence and stability and to which may be attached the elements of the ventilating canopy for proper positioning or alignment with the stove below the same. A further disadvantage has heretofore existed because of the fact that the screws, bolts or other "canopy securing means have not been readllyfacc'essible and considerable effort on the part or two or more workmen is required to be exerted to' h'old the canopy in place While securing it to the support.

The principal object of the present invention is to provide a ventilating canopy and mounting, the latter being designed for initial securerhe'nt to the studs of a wall, foll'owed'by the rear section of the canopy which is coextensive with the latter and shaped to define a housing for a suitable blower to influen'ce smoke and. fumes collecting under the canopy subsequently applied, out of the room through a convenient flue.

Another object of the invention is to provide a ventilating canopy in prefabricated sections in which the canopy itself as aseetion-can be independently mounted and subsequently-adjusted to align the same with the stove over which it is disposed and further to provide a canopy which can be kept clean because of the fact that all exposed areas likely to become soiled by smoke and grease may be conveniently 'reached from a standing position on the floor. Moreover, the canopy is devoid of inaccessible pockets and recesses in which dustand dirt may be entrapped.

With the foregoing objects in view, the invention has further reference to certain features of accomplishment which will become apparent as the description proceeds, taken 'in connection with the accompanying drawings wherein:

Figure 1 is a perspective view of a. ventilating canopy constructed according to the-invention.

Figure 2 is an exploded viewer the canopy assembly and mounting.

Figure 3 is a fragmentary pers'pective "view of 2 certain of the canopy sections showing the relationship in assembly.

Figure 4 is a fragmentary detail view in perspective of sectional wall protector panels and finish molding, and

Figure 5 is a view of the canopyassembly and mounting in vertical section.

Continuing with a more detailed description of the drawing reference numeral l'll'denotes each of a pair of parallel rails of the canopy mounting which are made of angle iron. These rails constitute the mounting for the canopy and associ-- ated elements to be later described.

It is important that the canopy be supported from the stable anchorage afforded by the studs of a wall rather than simply by the lath, wall board or other material forming the wall. Hence, when appropriate studs I'l (Fig. '5), of the wall are located, the rails ID are properly positioned and secured by affixing wood strips i2 to the studs 11 by nails l3 so that the ends of the strips l2 will bear on the confronting flanges of the rails in the manner shown. It is obvious that even after applying the rails In in the manner shown and described, they can be adjusted longitudinal- 1y, if desired, to properly position the canopy in relation to a stove below the'same.

The ventilating canopy consists of the main curved body I4 adapted to overlie a stove, the 'rear portion l5 being on a horizontal plane and provided on its rear edge with a return flange I'B. Subjacent the portion [5 oi the canopy T4 is a coeiitensive parallel portion ll which likewise has a return flange l8 the length of its rear edge. The portions [5 and ll of the canopy are held in fixed spaced apart relationship by metal straps l9 whoseupper ends are welded or'otherwise secured to the underside of the portion 15 while their lower ends are similarly anchored to the underlying portion ll which latter is formed by bending a sheet of metal at right angles, the vertical portion of which constitutes a panel 20, perpendicular to and underlying the upper portion l5of the canopy.

The panel 20 has an elongated opening 2| therein intermediate its ends through which air, smoke and odors are influenced by a suitable blower (not shown) housed in the chamber defined by the canopy sections l5, l1 and 20. The air, smoke and odors find escape through an opening 22 in the midsection of the canopy 'portion 15 with which communicates a flue, also omitted, leading to a chimney or other outlet.

Adjacent each end of the imiierlying canopy portion I1 is an opening 23 overwhich lamps are '35 and these strips are attached in the disposed so that the light emanating therefrom may illuminate the stove through the openings 23.

At each end of the canopy I4 is an end panel 24 whose upper edge is shaped to conform to the portion l of the canopy l4 as well as the curved forward portion thereof and whose lower edge has an upturned flange 25 as a grease trap. Similarly, the forward edge of the-canopy l4 has an upturned flange 26 to collect grease accumulating on the underside of the canopy.

Below each of the end panels 24 is a side wing 21 which has a right angle flange 28 along its.

upper edge which is adapted to be bolted to the flange 25 of the adjacent end panel 24. The lower edge of each side wing 21 converges to a point at its junction with the outer end of the canopy l4. The end panels 24 and side wings Z'Iserve to confine rising smoke and fumes under the canopy l4 so that they will be caught up in the current of air created by the exhaust blower in the enclosed portion of the canopy and carried off, as described. To provide a rigid support for the exhaust blower, the lower mounting rail [0 has affixed thereto a pair of spaced apart and forwardly projecting arms 29 secured thereto and stabilized by angular braces 38. The blower and operating motor are secured to the arms 29.

After first securing the mounting rails It to a wall, as previously described, the exhaust blower unit is set in position on the supporting arm '29 and secured. The canopy is then lifted into position so that the upper return flange It will rest on top of the upper mounting rail lil while the lower return flange l8 will bear against the underside of the lower rail [0 as shown in Figure 5. Each of the straps IQ of the canopy has a transverse slot 3| adjacent its upper and lower end and these slots receive threaded studs 32 affixed to and protruding from the rails l0. After the straps ['9 are properly located on the studs 32, nuts 33 are threaded onto the studs, access being had thereto either at the ends of the canopy or through the openings 23 in the portion i1 thereof.

It is apparent that by virtue of the elongated slots 3| in the straps I9, the canopy may be adjusted longitudinally before the nuts 33 are tightened finally andprior to installing the end panels and side wings. A considerable saving in time and labor is eifected by this provision but chiefly through the provision for the successive installation of the mounting rails, exhaust unit, canopy proper, the end sections and finally the wall panel 34 and side panels 35. As a result, one workman may install the ventilating canopy in the time formerly requiring the efforts of two or more workmen. V

The end panels 24 as well as the side wings 2! each have flanges 36 along their vertical rear edges. The flanges of the panels 24 lie under the ends of the mounting rails It to conceal them and 'present a pleasing finish while the flanges of the side wings 21 extend under the side edges of the side panels 35 at their upper ends.

The inner longitudinal edges 31 of the side panels 35 are each inset to underlie the contiguous side edges of the central wall panel 34 so that all of the panels will lie flush. This is true also of the upper ends of all of the panels 34 and 35 where they extend under the lower return flange l8 of the underlying canopy section ll, as shown, in Figure 5. j

Finish molding'strips 38 are provided for concealing the joints'between the wallpanels 34 and conventionalmanner as by clips 39.

By virtue of the fact that the exhaust unit housing extends the full width of the canopy I4, no inaccessible recesses or cavities are formed to collect dirt difficult to remove. All exposed surfaces on which grease and other foreign matter may collect can be readily reached by one to clean the same while standing on the floor, hence to keep the canopy in a clean and sanitary condition will require but a minimum of time and effort.

Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claims is also considered to be within the spirit and intent of the invention.
